ABSTRACT:
A pressure tap probe having a flexible probe tip that is flexible enough to seal a film cooling hole having a roughened surface such as a TBC applied around the hole. The flexible probe tip is flexible enough to deform around the film cooling hole such that an accurate pressure reading can be observed for the film cooling hole. The flexible pressure tap is used to measure the pressure at a plurality of film cooling holes on a turbine airfoil when a pressure and a flow rate of cooling air is passed through the airfoil. A plurality of film cooling holes are measured by using the flexible pressure tap to determine if the cooling passages and film cooling holes are properly sized to provide adequate cooling for the airfoil.
